VPP PERFORMANCE TESTS - - **Service density 2n-skx tests**: Added higher NF density tests with - 802.1q (vlan) and 802.1ad (vxlan) encapsulation from Traffic Generator. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. - - **GBP tests**: Added GBP routing test cases with 802.1q (vlan) external - traffic. + - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels. + See :ref:`geneve_methodology` for more details. - - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and scale - test cases. - - **2n-skx tests**: Increased coverage of selected (COP, iACL, Policer) - test cases. + - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio. + All tested topologies are compared with GSO enabled and disabled. + In |csit-release| there is only 1t1c tests running. + See :ref:`gso_methodology` for more details. - - **IPsec scale tests**: Added IPsec interface mode scale tests with - 1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 tunnels. Removed DPDK - backend dependency. - - **Hoststack TCP tests**: Added Hoststack TCP performance tests - using WRK to the HTTP static server plugin measuring connections - per second and requests per second. + - **NAT44 tests**: Added new test type, pure throughput tests. + They are similar to PPS tests, but they employ ramp-up trials + to ensure all sessions are created (and not timing out) + for performance trials. - - **Changed methodology of dot1q 2n tests**: dot1q encapsulation is now used - on both links of SUT. Previously dot1q was used only on a single link with - the other link carrying untagged Ethernet frames. This change results in - slightly lower throughput in CSIT-1908 for these tests. + - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled + in ipsec suites. + + - **Randomized profiles**: Improved repeatability and cycle length. + For details, see :ref:`packet_flow_ordering`. + + - **Arm 2n-tx2 testbed**: New physical testbed type installed in + FD.io CSIT, with VPP and DPDK performance data added to CSIT + trending and this report. + + - **Framework speedup**: Shortened overall test job duration + by using a different test selection mechanism (using --test + instead of --include) and by avoiding unnecessary PAPI reconnects. #. TEST FRAMEWORK - - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords to - PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components - of PAPI Executor and PAPI history. Currently the only exception is - usage of VAT command for scale configuration. + - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords and aligning of suite/test - setup/teardowns. + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests. See known issues below. + - **General Code Housekeeping**: Ongoing code optimizations, + speed ups and bug fixes. #. PRESENTATION AND ANALYTICS LAYER - - **Graphs Layout Improvements**: Improved performance graphs layout - for better readibility and maintenance: test grouping, axis - labels, descriptions, other informative decoration. + - **Graphs improvements**: Updated Packet Latency graphs, + see :ref:`latency_methodology`. .. raw:: latex @@ -60,15 +64,40 @@ Known Issues List of known issues in |csit-release| for VPP performance tests: -+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+ -| # | JiraID | Issue Description | -+====+=========================================+==========================================================================================================+ -| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
